Top Secret Diet was Given to U-2 Pilots So They Wouldn’t Have To Poop or Pass Gas

U-2 “spy-in-the-sky” plane played a legendary role in aerial espionage over China, Soviet Russia, and other countries during the Cold War.

But the aircraft was notoriously difficult to pilot and physically demanding which involved flying over ten hours at high altitudes in a go, taking pictures and dodging missiles without a bathroom or ventilation.

Though the spy plane was equipped with a ‘relief tube’ for urination but there was no system installed for defecation.

To cope up with this problem, CIA prescribed a diet for U-2 pilots to avoid the need to poop or pass gas. The purpose of this “high protein, low residue” diet which can be almost completely absorbed from the gastrointestinal tract, was to minimize poop creation.
